Hiroshi Goto, Shunichiro Ueda
AIMS: Immunoglobulin G4 (IgG4)-related disease is known to have diverse clinical manifestations. We report a case of IgG4-related ophthalmic disease misdiagnosed as intraocular tumor. METHODS: Case report. RESULTS: A 41-year-old man was referred to our department with a diagnosis of intraocular tumor, presumably choroidal melanoma. Although MR imaging was compatible with choroidal melanoma, he had been observed periodically without treatment because fundus findings were not typical of melanoma and visual function was preserved...

High-mobility group A2 (HMGA2) protein regulates retinoblastoma (RB) cancer cell proliferation. Here, a stable phosphorothioate-modified HMGA2 aptamer was used to block HMGA2 protein function in RB cells. HMGA2-aptamer internalisation in RB cells (Y79, Weri Rb1) and non-neoplastic human retinal cells (MIO-M1) were optimised. Aptamer induced dose-dependent cytotoxicity in RB cancer cells (0.25-1.5 µM). Increased expression of TGFβ, SMAD4, CDH1, BAX, CASP 3, PARP mRNA and decreased SNAI1, Bcl2 mRNA levels in aptamer-treated RB cells suggests the activation of TGFβ-SMAD4-mediated apoptotic pathway...

We report a case of a choroidal neovascular membrane (CNVM) associated with sclerochoroidal calcification (SCC). An asymptomatic, 72-year-old male was referred to our institution for yellow-white placoid retinal lesions of both eyes. B-scan ultrasonography confirmed the diagnosis of SCC, and indocyanine green angiography confirmed the presence of an associated CNVM. Due to enlargement of a hemorrhagic pigment epithelial detachment associated with the CNVM over the course of 7 months, the patient was treated with a series of bevacizumab injections followed by photodynamic therapy (PDT)...

Neurothekeomas (NTKs) are benign cutaneous neoplasms of fibrohistiocytic origin and most commonly occur in the head, neck, and upper extremities. Traditionally, NTK and nerve sheath myxoma (NSM) were classified as subtypes of a single neoplasm with a common histogenesis, but recently immunostaining has demonstrated that the lesions are most likely of distinct cellular origin. Rarely, NTKs have been reported to occur in the ocular adnexa, and the present case of a 39-year-old female is the first to describe a cellular NTK originating in the cornea and mimicking a Salzmann's nodular degeneration...

Gnathostomiasis is a parasitic disease caused by nematode larvae ingestion of 15 known species of the genus Gnathostoma (one of the Gnathostomatidae family members). This parasite uses freshwater fish as a host and can infect - through the consumption of raw fish or their viscera - other animals such as dogs, cats, chickens, pigs, and humans. This parasitic disease, with humans acting as hosts, has been known since 1945 (India), and ocular complications have been known since 2004 (intravitreal; also described in India)...
